List packaged sample data assets
AI agents call sample_data_catalog to retrieve information from ContextForge MCP Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation (listing/retrieving) of sample data catalog metadata. It has no side effects, does not execute code, does not modify data, and does not involve financial transactions. The blast radius of misuse is minimal—an agent could only enumerate available sample datasets. Classification as Read is appropriate.
From the tool's definition Tool name 'sample_data_catalog' combined with description 'List packaged sample data assets' indicates a query/listing operation that retrieves information about available sample data without modifying or executing anything.

sample_data_catalog is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the sample_data_catalog rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
